Abstract
A method and system facilitate telephony over computer based networks. The parties to a telephone call need not have the same telephone application software capabilities before the call is initiated nor does the network have to provide standard signaling. Instead, in accordance with the method and system one of the parties defines to the other party the encoding/decoding technique to be used in the processing of the call. The definition can be either by supplying a copy of the application to the other party or by providing the other party with an indirect reference to where the application can be obtained.
